This is how I do it. No VPN. No NAT nonsense. You can open an IPv6 address to the public internet and nobody is going to stumble across it. You don’t even disclose your address to servers you connect to.

100% of shady connections come from bots scanning address space on IPv4.

Data is stored on a hard disk. You can steal those.

However, this sounds more like the “transfer me your crypto or I’ll bash ya” kind of old school thuggery.

Anyone with a crypto wallet on a hard disk would have it encrypted, backed up, and paasworded too. Stealing the physical disk would only work if you also had means to break into it, and transfer the funds faster than the owner can do the same from their backup.
